AT3™ FU-BAG™ AR-15 Lost Parts Kit – Springs, Detents, Replacement Components


Timber Creek Outdoors Ambidextrous Safety Selector - Black


Enhance your AR with a superior trigger and grip with AT3 and Magpul

This high quality lower parts kit features our AT3 Enhanced Nickel Teflon Trigger, with a Magpul MOE Pistol Grip and optional MOE Trigger guard.

This kit is great for any AR builder who wants quality components without breaking the bank, with the ergonomics of Magpul’s pistol grip combined with our Nickel Teflon Trigger Assembly. The trigger has a smooth pull and clean break unlike a standard trigger, and the MOE trigger guard allows more room for comfortable shooting with gloves.

This kit will save you 15% on your Magpul grip when you buy this kit, and 20% when you add the trigger guard!

Great Kit!

Great kit. Good as or better than PSA's, but unlike PSA, AT3's kit is $35 less, free shipping, and includes a parts list with instructions.

The only place to buy it.

Thanks for sharing your feedback! We're glad you're satisfied with your purchase. Cheers!

Joseph Benson
Love it

The only thing it didn't come with the trigger guard roll pin but it came with a trigger guard I ordered so all is well. Trigger feels great. Works flawlessly

Christopher Rigoli
Love AT3 and the products.

The kit is simple, instructions are clear and parts are marked on a sheet.

Fast shipping great customer service. Can’t say anything bad about this set up so far.

Thanks for sharing your feedback, Christopher. We're glad you're satisfied with your purchase. Cheers!

James Coleman
Great Parts Kit

Bought the kit to help build my girlfriends lower. Came with everything that was listed and everything went into place perfectly. Can’t wait to finish the build with her

Thanks for sharing your feedback, James. We're glad you're satisfied with your purchase. Cheers!

Reginald Silver
Excellent product

This is my first Ar build and it only took me 1 hour to put the lower parts kit into my receiver. The trigger feels great. I'm giving this kit a 4 star rating simply because I wish the parts were packaged in a way to easily identify which parts went with which springs and so on.

Thanks for sharing your feedback, Reginald. Your comments were all noted. We're glad you liked it.
